Removing Rust Stains from AC Drip Lines in Katy, TX

Here in Katy, Texas, we see this problem all the time — rust stains running down the side of a home from an air conditioner drip line. It’s common in our humid climate, and while it might look like permanent damage, it can be professionally cleaned with the right products and technique.

This homeowner noticed deep orange streaks running down their brick and Hardie board siding from the AC drip line. Rust stains like these can’t be removed with regular pressure washing alone. Instead, we use a specialized rust removal treatment designed to break down the iron deposits without damaging the surface.

Once treated, the stains lift away, restoring the home’s natural color and curb appeal. Rust removal requires skill and the correct cleaning agents—using the wrong method can permanently etch or discolor your brick and siding.

Why Rust Stains Happen

  • AC drip lines can carry trace minerals that oxidize over time.
  • Sprinklers or irrigation systems with high iron content can leave rust marks.
  • Metal fixtures near siding or brick can also cause rust runoff.

Why You Should Get Rust Professionally Removed

  • Prevents long-term staining and discoloration.
  • Protects your home’s exterior surfaces.
  • Instantly boosts curb appeal.
